Specification of Letters Patent.

Patented July1,-i913.

Application filed August'ZS, 1910. Serial ltd-578,553.

'liibbing, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Dumping- Cars, of which theffolowii is a specification.

My invention relates to dumping cars of that class wherein the car is tilted or turned toward one side or' the other in order to discharge. its load, the car being provided with side boards adapted to be raised to permit the contents of the car to be discharged. In cars of this description the car body is ordinarily pivotally supported upon the center of the trucks from end to end and at a considerable distance above the trucks. Being so supported, it is evident that means must be provided for supporting the car body in a substantially horizontal position at all times except when the contents of the cars are being dumped.

The primary object of my invention is the provision in combination with rigid supports pivoted under the car body at the sides thereof, of means for latching or looking the supports in a vertical position, and prevent-- ing the supports from being accidentally moved or shifted into such position that the weight of the load would tend to tip the car bodylaterally to a dumping position.

urther object is the provision of means which not only tends to lock thelateral supports in a vertical position, but also provides mpans whereby the supports may be readily operated from the side opposite to that on which the load is to be discharged.

One of the difliculties ordinarily found in constructions of this character is thatit is necessary in order to move the supports on one side of the car that the workman be on the side of the car toward which the load isto be dumped. By my invention, the workman may stand upon the opposite side of the car to that where the load is to be dumped and operate the dumping mechathereby protecting the workman against injury due to the discl'largc of the load upon or around him.

My invention is shown in the accompanying drawings, wherein Figure 1 is a side elevation of a railway dumping car with my invention applied thereto.

Fig. 2 is an end elevation of the dumping car shown in Fig. 1, the body of the car being tilted. Fig. 8 is a perspective detail view of one of the pivoted supporting members. Fig. 4- is a side elevation of the locking device, the rock shaft on which it is supported, and the beamsQ-and 5 being in-section.

As" illustrated in Figs. 1 and 2 the body of the car is mounted on longitudinally extending sills 2. These, together with the transverse sills 3 form a base frame which is supported in any suit-able manner upon wheeled trucks. Supported upon the transverse sillsor beams 3 are the longitudinal beams 5 disposed in parallelrelation on each side of the central longitudinal axis of the car body. The'floo'r of the car 6 is supported and braced by oppositely disposed parallel longitudinally extending beams '7 and transverse beams 8. Mounted upon the base formed by'theparallel beams 5 are a:plurality of. upwardly projecting-standards 10 and extending down from the floor of the car, andpreferably mounted upon the cross beams 8 are the supporting members 11 which are pivotedat-their lower-ends to the standards 10 by pivot pins 18 passing =through the oo'sacting ends of the standards. Theb-ody of the car isthus' supported for a laterally-tilting movement in either direction. I

For the purpose of supporting the car body in a horizontal plane. or tipping it to either side, the following instrumentalities are provided. Pivotally mounted on the beams 2 are a plurality of supporting mem- 'bers 14, one of which is illustrated in Fig.

3. A series of these supporting members are disposed on each'of the beams 2, the supporting members on one beam beingoppositely disposed with relation to the supporting members on the opposite beam so that the saidsupporting members 14 will support both sides of the car body when both sets of supporting members are turned to a vertical position.

The upper end of each supporting member 14 on one side of the car is connected by a link 15 to an arm 16 mounted upon a rock shaft 17 mounted in hearings on that one of the beams 5 which is adjacent the other side of the car. There'are, therefore, two rock shafts 17 each of which is mounted upon one of the beams 5, the rock shafts being located one on each side of the standards 10. These rock shafts extend along the entire length of the car and the arms 16 are rigidly engaged with the rock shafts so as to turn therewith. Each arm 16 is pivotally connected to the corresponding link 15 by a transverse pin or other suitable connecting means 18. The link 15 is in turn pivotally connected to the upper end of the supporting member 14 in any suitable manner.

Preferably each of the supporting members 14 is formed as shown in Fig. 3, of two oppositely disposed bars each having a bracket 20 and held in proper spaced relation to each other and rigidly braced by a transverse web 21 riveted to the bars 14. The brackets 20 and the upper ends of the bars 14 form bearings for the trunnions 24 of an anti-friction roller 22. The terminal of the link 15 is received and pivoted by the trunnion 24, the link 15 being bifurcated at its adjacent end so as to straddle the roller 22.

1: 5 so that when this arm 16 is turned to a horizontal position by the rotation of the rock shaft, as shown in Fig. 2. the arm 16 will lie horizontally and restupon the corresponding beam 5.

It will, of course, be noted, that the arms 16 on one side of the base are connected to the supporting members 15 on the opposite side of the car, and that therefrom the arms cross each other. \Vhen either rock shaft isrotated to its full extent in one direction the links 15 and 16 will be in approximate alinement and the supporting member 14 will be raised to a vertical position, the roller 22- thereof bearing against the under face of the corresponding beam 8. When, however, the rock shaft is turned in a reverse direction, that is, in the position shown on the right hand side of Fig. 2, the arms 16 will be moved upward and outward and the links 15 connected thereto will be retracted.

The standards 1.4 on the opposite side of the car from the last named rock shaft will be turned to an inwardly inclined position, and there being no supporting end on that side of the body of the car the weight of theear body willl cause it to tip, as shown in Fig. 2. After 1e load is dumped the. car

' body may be again lifted to a horizontal po sition by rotating the rock shaft on the side and in dotted lines in the car body, which will throw the arms 16 upward and inward, which will push out ward on links 15,move the supporting members 14 outward and upwardly, and cause the anti-friction members 22 to contact with the beams 8 on the bottom of the car body, thus porting members are vertical, the arm 28 on eachtrock shaft extends upward and slightly inward, as shown in Fig. 4. When, however, the rock shaft to which the arm 28 is attached is rocked to dump the car, the arm takes the position shown in full lines in Fig. 2.

Pivotally attached to the extremity of the curved arm 28 is the downwardly extending latching-member 29 which is formed at its lower end with a tooth 30' adapted to engage with the angle extremities 31 of a plate 32 which is attached to the upper face of the adjacent sill 2.

It will be noted that the member 29 is sufficiently longer than the member 28 so as" to hold this member 28 turned slightly in-- It will be noted from Fig.2 that when one of the standards 14 is'in a vertical position the corresponding arm 28 and member 29 will be in the positi 11 shown in Fig. 4.

that in this position of the parts the corresponding link 16 on the opposite side of the car will lie fiat down upon and bear on the beam 5 and that any inward thrust upon the corresponding link 15 .will be exerted in a ig. 2, and further line which if extended will pass below the corresponding rock shaft 17, so that any inward movement of the standard 14 and the connecting link 15 wilLforce the connected arm 16 down firmly upon the corresponding -beam 5 and that, therefore, the parts, when in .this position, will be locked from any inward movement until the proper rock shaft is actuated and thearm 16 is locked from any ,upward and outward movement which will act to rotate the rock shaft 17, thus- .65 of the car opposite the depressed portion of 1-'withdrawing the connected supporting meIn-- bers 14' from their supporting position turning them upon their pivots into the position shown in the left hand side of Fig. 2, and ptgmitting the car to tip downward on that S1 G.

By the use of my invention there is absolutely no danger of the" car accidentally dumping of tipping, nor is there any danger of t e car dumping or tipping toward the side where the operator is standing. The operator is obliged always to operate the dumping mechanism from the side oppo site to that Where the material is dumped, thus all'chance of accidents is obviated.

Wliile' I have illustrated in Fig. 2 a construction and arrangement of devices for causing a raising and lowering of the mov able side boards of the car, this is simply to complete the illustration of the car, and a description thereof is not necessary inasmuch as this is a common and well known' construction thoroughly understood by those skilled-in the art.
